This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/496,972 filed Aug. 20, 2003 entitled “Walker Distance Measuring Device,” the entire specification of which is hereby incorporated by reference.
1. Field of the Invention
The present invention relates in general to medical measuring devices, and more particularly, to a walker distance measuring device, and, in turn, an associated method for measuring distances moved by patients associated with walkers.
2. Background Art
Many individuals, due to injury, ailment or age are confined to wheelchairs and/or walkers which either fully assist with transport, or which at least partially assist with movement and transportation. While such walkers and wheelchairs facilitate movement and mobility, there are certain issues which arise from the operation of same. For example, often those confined to such walkers and wheelchairs have a difficulty quantifying movement and quantifying the travel they have undertaken with the walker and/or wheelchair.
Thus, it is an object of the invention to provide a measuring device which facilitates measurement of the distance one has traveled with a walker and/or wheelchair.
Other objects will become evident in light of the specification and claims appended hereto.
The invention comprises a walker and/or wheelchair distance measuring device. The device comprises a wheel assembly, a measuring assembly and a display. The wheel assembly is capable of attachment to a walker. The wheel assembly includes a support and a wheel. The measuring assembly comprises a sensor and a processor. The sensor includes a trigger associated with one of the support and the wheel and a pickup associated with the other of the support and the wheel. The processor is electronically coupled with the sensor and the processor is capable of interpreting the information received from the sensor. The display is associated with the processor for displaying results computed from the processor.
In a preferred embodiment, the trigger is associated with the wheel and the pickup is associated with the support.
In one such embodiment, the pickup comprises a first pickup and a second trigger. The first and second triggers are positioned along the wheel spaced apart a predetermined arcuate distance from each other.
In another one such embodiment, the display is capable of displaying at least one of distance traveled, speed, total distance traveled, average speed.
In another preferred embodiment, the display comprises a LCD display.
In another preferred embodiment, the invention further comprises memory associated with the processor. The memory is capable of storing data pertaining to the movement of the walker.
In one such embodiment, the invention further comprises an output associatable with an outside device which is capable of retrieving data stored in the memory.
The invention will now be described with reference to the drawings wherein:
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will be described in detail, a specific embodiment with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated.
It will be understood that like or analogous elements and/or components, referred to herein, are identified throughout the drawing by like reference characters. In addition, it will be understood that the drawing is merely a schematic representation of a first embodiment of the invention, and some of the components may have been distorted from their actual scale for purposes of pictorial clarity.
Referring now to the drawings, and to
As is shown in
Axle 24 extends through the lower end of attachment device 20 capturing wheel 26 therebetween. Indeed, wheel 26 is permitted to rotate about axle 24. The wheel generally includes a wheel comprising plastic and rubber. It is contemplated that the wheel comprises a predetermined circumference, such as 6 inches in the preferred embodiment. Of course, any number of different sizes and configurations are contemplated.
As is shown in
Processor 32 is capable of receiving the sensor readings from sensor 30 and is capable of computing the distance traveled by the wheel's outer perimeter. The processor may be associated with volatile and/or non-volatile memory 52 so as to retain the data that is collected. The processor may be associated with output 38. Additionally, an output can be provided for transferring the data from the memory to another device, such as a PDA or a computer. In the embodiment shown, the sensor is wired to the processor which is contained within housing 40. In other embodiments, the sensor can be wirelessly associated with the processor through various means, including, but not limited to RF, Bluetooth, IR, etc.
Display 16 is shown in
The foregoing description merely explains and illustrates the invention and the invention is not limited thereto except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications without departing from the scope of the invention.
